3D EBSD Dataset of the Alpha and Beta Phase Orientations for a Hot-Rolled Model Zircaloy-4 with 7 wt.% Nb Alloy
<p>A set of serial-section electron backscatter diffraction (EBSD) data files and a 3D reconstruction of a model Zircaloy-4 with 7 wt.% Nb addition alloy following hot-rolling.</p> <p>The 3D data set contains measurements of the material rolled at 725C to 75% reduction. The measurements include indexing of both the alpha and the beta phases in 441 sequential slices, each of 0.1 μm, through a small section of the material, taken using the dual beam Thermo Scientific Helios Xe<sup>+</sup> plasma focused ion-beam scanning electron microscope (PFIB-SEM). The 3D EBSD data set includes EBSD measurements in the form of ctf files, binary data files, an Aztec project file, and accompanying images for each slice.</p> <p>A 3D volume was reconstructed from the 3D EBSD data set using a customised pipeline within the DREAM.3D software. The results of this analysis are included in the 'dream3d' folder, which includes a description of the pipeline, the final fully reconstructed dream3d data file, an xdmf file used for visualising the data in ParaView, a h5ebsd file containing results for the reconstruction, and grain averaged data for each of the identified features.</p> <p>Please see our accompanying paper for analysis of the 3D reconstruction - as well as analysis of the 2D measurements from <a href="https://doi.org/10.5281/zenodo.3784460">10.5281/zenodo.3784460</a> - and for interpretation of the coupled crystallographic texture evolution;</p> <p>C.S.

Rubble Biodiversity Samplers (RUBS): 3D-printed coral models to standardise biodiversity censuses
<p>1. To ensure standardised, quantitative and repeatable methodologies, marine ecologists have engineered a range of artificial units to survey benthic communities with varying designs depending on target taxa, life history stage and habitat. In tropical ecosystems, autonomous units have typically lacked microhabitat complexity (e.g. planar tiles), short-term efficacy (> 1 y deployment) and/or a truly standardised design to sample cryptobenthic diversity.<br> 2. Coral rubble is characterised by high microhabitat complexity, which is unresolved in sampling efforts. Yet, rubble can support the greatest density and diversity of metazoan taxa.<br> 3. We engineered Rubble Biodiversity Samplers (RUBS) as a dismantlable lightweight 3D-printed model to standardise cryptobenthic biodiversity sampling.<br> 4. We demonstrate the effectiveness of RUBS with preliminary results from short-term (1–14 days) deployments in Palau, Western Micronesia.<br> 5. RUBS uphold the microhabitat complexity inherent in coral rubble (~50% interstitial space) and provide an effective and efficient methodology to sample cryptobenthic fauna, which could be applied in comparative studies.<br> 6. The RUBS concept provides a platform for the broader implementation of 3D-printed models in marine ecology to overcome issues of standardisation regardless of habitat type.</p>
Pitfalls of Computed Tomography 3D Reconstruction Models in Cranial Nonmetric Analysis
<p>Many studies in the literature have highlighted the utility of virtual 3D databanks as a substitute for real skeletal collections and the important application of radiological records in personal identification. However, none have investigated the accuracy of virtual material compared to skeletal remains in nonmetric variant analysis using 3D models. The present study investigates the accuracy of 20 computed tomography (CT) 3D reconstruction models compared to the real crania, focusing on the quality of the reproduction of the real crania and the possibility to detect 29 dental/cranial morphological variations in 3D images. An interobserver analysis was performed to evaluate trait identification, number, position, and shape. Results demonstrate a false bone loss in 3D models in some cranial regions, specifically the maxillary and occipital bones in 85% and 20% of the samples. Additional analyses revealed several difficulties in the detection of cranial nonmetric traits in 3D models, resulting in incorrect identification in circa 70% of the traits. In particular, pitfalls included the detection of erroneous position, error in presence/absence rates, in number, and in shape. The lowest percentages of correct evaluations were found in traits localized in the lateral side of the cranium and for the infraorbital suture, mastoid foramen, and crenulation. The present study highlights important pitfalls in CT scan when compared with the real crania for nonmetric analysis. This may have crucial consequences in cases where 3D databanks are used as a source of reference population data for nonmetric traits and pathologies and during bone-CT comparisons for identification purposes.</p>
